Bridge mode does not do what is explained
I had an older arris modem and used it with my night hawk r7000 and it worked great. I got about 100mbps over wifi. The built in wifi did not work well for the size of my house so I used my night hawk. The modem started having problems so xfinity gave me a new modem. Again the modems wifi did not work well, so I used my night hawk and again it worked, but the speed was much slower (20mbps). I spoke to xfinity and they said in order for my router to work to it potential I needed to enable the wifi bridge mode to turn off the modem wifi and enable the potential of my wifi. It made sense so I went into the admin settings and enabled the bridge mode. This actually stopped all my wifi routers from connecting. I even tried using my google hub and same thing. When I disabled the bridge I was able to use it again. I think there is some confusion with xfinity. Any idea what is going on and why bridge mode disables my wifi routers from connecting to the internet?
